Sympathies to the originator of this thread. I also have an RM Ascend 2020B. Its an all-in-one PC in a BLACK plastic case and is a real puzzle. Can not get the case open and I am not a newbie. I have been building/repairing PCs for 15 years and this case, along with the lack of support documentation, is driving me mad.
IU only want to up the memory but how to open the case?
